BASMUS HAGBARIH QUISLING, OF OHRISTIANIA, NORWAY.

FUSE -AD JUSTING DEVICE To all whom it may concern:

Be it known that I, RAsMUs HAoBARri-r QUISLING, a subject of the King ofNorway, residing at Christiania, Norway, have invented certain new anduseful Improvements in Fuse-Adjusting Devices; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Devices for timing time fuses as hitherto used have either been designedfor fuses with only two fuse rings, in which case, consequently, onlyone fuse ring is actuated, or, if more than two fuse rings have beenused, the timing rings have been so connected, that the action of thetiming device remains the same, 2'. c. with only one point ofapplication for the timing movement.

My invention relates to a time fuse with more than two fuse rings,whereby, consequently, in being timed, two or more fuse rings are to beimparted the same angular movement, and a timing device for the same.This device is so constructed, that, by the manner in which it isarranged on the fuse, it will be automatically secured to the same andclamp those fuse rings, which to time the fuse must be turned throughthe same angle.

In the accompanying drawings Figure 1 is a partial longitudinal sectionof my improved wrench applied to one form of fuse which latter is shownin elevation. Fig. 2 1s a plan view of the same. Fig. 3 is a horizontalsection of the rlngs. Figs. a and 5 are respectively an elevation andplan of a modified form of wrench and fuse and Figs. 6 and 7 are likeviews of another modification.

In Figs. 17 the device is shown in the form of a conic sleeve (I-I)embracing the fuse body up to such a height that it may clamp the fuserings to be turned and at the same time obtain the stability requiredfor the accuracy of the movement. On one side it is provided with anumber of projections (11 and 13), corresponding to the number of thetiming rings (here 2), and on the opposite side with a handle (8) and anotch (4;) to enable the sleeve to be attached to the fuse in a mannerthat will insure a proper Specification of Letters Patent.

function of the device. In Figs. 13 is shown an executional form, wherethe said sleeve is applied in connection with an automatic timing wrenchas an integral part of the inner ring of the wrench or key, whereby isobtained an automatic timing wrench for fuses with more than two fuserings.

In Figs. &7 are shown another two executional forms embodying myinvention designed for reading for each separate timing. In Figs. 4t-5the scale is disposed on the fuse and a movable index on the timingdevice, while the form of apparatus shown in Figs. 6-7 has the timingscale at the foot (6) of the timing device and an index integral withthe fuse (7).

The device is worked in the following manner: The device, in an inclinedposition to the longitudinal axis of the projectile, is slipped over thehead (point) of the fuse, until the lower projection (11) has enteredthe corresponding notch. The handle is thereupon turned downward in theplane through the axis of the projectile with the said projection as afulcrum, until the upper projection (or projections) has entered thecorresponding notch and the sleeve attained a firm grip around the fuse.Thereupon the handle is turned in the timing direction, until it stopsagainst the projection (notch) of the fuse, or until, by reading on thescale, a correct timing has been ascertained. The device is removed fromthe fuse by the same operations as used in applying it to the fuse, butin opposite order.

It appears from the way of action of the device that in the form ofexecution shown in Figs. l3 the upper projection (or notch) may beinclined in the opposite direction to the direction of the timingmovement (13 and 14), as the automatic timing wrench is turned only inone direction, while those devices necessitating direct reading for eachseparate timing should also allow the fuse rings to be moved in bothdirections and therefore in that case both lateral faces of theprojections must be square to the surface of the fuse. Thenotches'particularly those of the upper rings-should be broader than theprojections which by means of insections (slots) in the sleeve, parallelto the axis of the fuse (sleeve), may in some degree be caused to act asa spring. Instead of providing the timing device with projections andthe fuse rings with notches I may also provide the timing device withnotches and the fuse rings with corresponding projections.

Claims 1. A timing device for time fuses having more than two fuserings, comprising asleeve provided with engaging means adapted to engagecooperating means on the rings of a fuse said sleeve having a notch inits upper edge whereby the device may be inclined relatively to thelongitudinal axis of the fuse to permit first the engagement of thelowest engaging means and the subsequent engagement of the upperengaging means.

A timing device, for time fuses having more than two fuse rings,comprising a sleeve provided with lugs adapted to take intocorresponding recesses in the rings of a fuse, said sleeve having anotch in its upper edge whereby the device may be inclined relatively tothe longitudinal axis of the fuse to permit the lowest lug to firstengage the lowest notch.

In testimony that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
